I tried it, and I bought an earrings that "supposedly" be worth about $170 bucks for 50 cents + 7 bucks for shipping. My friend got a new ipad for 60 bucks. But overall, I wouldn't recommend it because it's pretty much gambling which is addictive and waste of money.

If you really want to try it yourself, try bidding during night time because at night, it has less competition.
